Description

[0001] CATHETER APPARATUS FOR NUCLEOPLASTY USING HIGH FREQUENCY AND LASER [0002]

The present invention relates to a catheter apparatus for decompression using radio frequency and laser, and more particularly, to a catheter apparatus for decompression using a high frequency and a laser, which enables a practitioner to continuously perform high frequency and laser procedures while confirming a lesion site in real- Catheter decompression catheter device.

In general, posterolateral endoscopic discectomy (PED) is a surgical approach that is performed from the posterior approach of the intervertebral disc.

The posterior region of the disc is called the Triangluar Working Zone and is an equilateral triangle shaped Kambin Zone (KZ) covering the posterior side of the disc as shown in FIG.

The triangle constituting the triangular working area is composed of hypotenuse, base, and height. The hypotenuse is the exiting nerve that exits the intervertebral column. The base is the lower vertebra and the height is the traversing nerve.

When the disc is lowered diagonally, the annulotomy area consists of the upper proximal part of the lower part and the upper part of the lower part of the lower vertebra.

The spinal cord nerves forward from the intervertebral column to the front of the triangle.

At the end of the 20th century, the concept of microscopic disc surgery was introduced. In 1983, Kambin devised an endoscope with a diameter of 2.7 mm that could be inserted into the spine. The endoscope was capable of observing the spinal cord and nerve, And the so-called 'Triangluar Working Zone'.

Endoscopic discectomy, which removes the esophageal nucleus that compresses the nerve under this endoscopic view, is performed through a small tube that penetrates the skin without resection of the skin, muscles, and bones.

The patient who can apply the procedure is a patient who complains of nerve pain, and the cause must be the escaped disc disease.

Among these endoscopic discectomy procedures, the decompression of the nucleus using high-frequency heating is performed as shown in FIG.

8A, an opening is formed from one side of the disk 400, that is, the back of the subject, and the high frequency device 20 is pushed into the inside of the inside of the inside of the inside of the inside of the inside of the inside of the inside of the inside 410, And then heated to a predetermined temperature by high-frequency heating as shown in Figs. 8 (b) and 8 (c) to vaporize the escaped nucleus.

Thereafter, when the pressure of the disk 400 is lowered, the lesion site 420 is removed and restored as shown in FIG. 8 (d).

However, such conventional decompression of the nucleus pulposus decompression procedure is performed by using the high frequency device 20 and then inserted into the laser device (not shown) separately to release the stenotic tissue around the nerve around the disc 400 Also,

Therefore, it takes a lot of time to prepare a procedure and a procedure, and it is very inefficient in terms of time and cost since separate devices must be provided.

The guide portion 630 includes a passage guide hole 631 penetrating the front side end portion of the main housing 110 and a plurality of parallel guide passage holes 631 formed along the inner circumferential surface of the passage guide hole 631, And a passing flat portion 632 formed to have a constant width along the direction in which the guide portion 130 retreats or advances.

Here, it is understood that the moving step portion 625 of the guide pipe 130 faces the passing flat portion 632 in close proximity.

Accordingly, when the operator rotates the dial 610 in one direction as shown in FIG. 1B and FIG. 5, the operation of the rotation guide pipe 615, which rotates integrally with the dial 610 in the forward and reverse directions, The mover 622 will retract or advance in accordance with the screw movement of the second screw thread 623 coupled with the first screw thread 621. [

At the same time, the guide pipe 130 has a passage guide hole 631 of the guide portion 630 passing through the front of the main housing 110 and a guide hole 631 of the guide portion 630, which are formed by the length of the moving stepped portion 625 engaged with the moving flat portion 624, It can be retracted or advanced while being guided by the passing flat portion 632.

As described above, according to the present invention, a single device enables a practitioner to continuously perform high frequency and laser treatment while confirming a lesion site in real time, has versatility, and can apply various treatment tools to various treatment fields doing

It is understood that the basic technical idea is to provide a catheter device for decompressing the nucleus using high frequency and laser.

It will be apparent to those skilled in the art that many other modifications and applications are possible within the scope of the basic technical idea of the present invention.
